Injection molding machine’s Mechanical safety devices include interlocking guards, mechanical locking devices, emergency stop buttons, and so on.They work together to assist in all aspects of worker safety while the injection moulding machine is in operation.
The mechanical safety of injection moulding machines is installed at all angles on the sheet metal part of the machine’s outer contour, with the aim of setting up a ‘red line zone’ for the operator to ensure maximum safety.
The emerging Industry 4.0 in injection moulding brings a lot of convenience to large-scale manufacturing and reduces the number of people working on the shop floor, but even so, a number of operators are still retained. Safety is particularly important when operating machines such as injection moulding machines. Machinery insurance is the last line of defence for them on injection moulding machines.
Let’s have a better understanding of the mechanical insurance equipment for injection moulding machines!
A brief description of the structure of the three main mechanical insurances
- Interlocking guards
- Mechanical Locking Devices
- Emergency Stop Button
Interlocking guards
In the mould area and in the area of the clamping mechanism, interlocking guards.
Light curtains or fixed guards are required to prevent the operator from coming into contact with dangerous moving parts.
When the interlocking guards are open, all movement should be interrupted to ensure safety.
Mechanical Locking Devices
Injection moulding machines are usually equipping with mechanical locking levers and locking mechanisms that protect the operator by preventing accidental opening when the mould is closed.
Emergency Stop Button
In the event of an emergency, the operator can immediately press the emergency stop button to stop the machine from running to avoid potential danger.
How does the mechanical safety device work
The mechanical safety device of an injection moulding machine is an important mechanism used to ensure operational safety.
Its main function is to prevent the injection moulding machine from performing a closing action if the safety door is not closed.
Thus avoiding possible injuries to the operator.
Specifically, the mechanical safety device of an injection moulding machine usually consists of the following parts:
- Mechanical safety bumpers and stops
- Bumper and safety stop
- Chain mechanism
Mechanical safety bumpers and stops
When the safety door is open, the mechanical safety bumpers move, causing the mechanical safety stops to drop.
Thus preventing the movement of the mechanical safety lever.
This design ensures that the injection moulding machine cannot perform a mould closing action without the safety gate being closed.
Bumper and safety stop
While the safety door is open, the bumper moves out of the bumper cover and the safety stop falls down.
This action preventing the moving mould plate from closing.
If the other mould closing mechanism fails when the safety door is open, the bumper will quickly hit the stopper.
Then further preventing the mould closing action.
Chain mechanism
The mechanical safety device of the injection moulding machine forms a chain relationship with the hydraulic safety brake device and the electrical safety brake device.
When the safety door is opened, the three safety brakes work simultaneously, preventing the injection moulding machine from functioning.
And when the safety door is closed, these brakes are released and the injection moulding machine can be operated normally.
Through these mechanisms, the mechanical safeties of the injection moulding machine effectively prevent dangerous situations caused by mechanical or electrical failures and ensure the safety of the operators.
Mechanical safety devices for Haichen injection moulding machines
The high quality of the mechanical safeties of Haichen injection moulding machines is mainly reflected in the design and function of their safety protection devices.
According to the evidence, injection moulding machines are usually equipped with mechanical safeties.
Which are mounted above the front of the safety door and are used to prevent human injury in the event of mechanical or electrical failure during the production process.
These mechanical safeties include components such as bases, bumpers, mounts, safety stops, etc.
Which need to be regularly inspected to ensure their robustness and reliability.
In addition, injection moulding machines are equipped with hydraulic safety brakes and electrical safety brakes.
Which form an interlocking relationship with the safety doors to ensure operational safety.
When the safety door is open, these safety brakes act to prevent the injection moulding machine from operating.
When the safety door is closed, these mechanisms are released, allowing the injection moulding machine to operate normally.
The safety brake mechanisms are designed in such a way that they can be used to stop the machine from operating.
This design ensures that machine operation can be stopped quickly in the event of an accident, thus avoiding potential safety risks.
Therefore, the high-quality mechanical insurance of Haichen injection moulding machines is not only reflected in their complex mechanical structure but also in the design of their multiple safety protection mechanisms, which ensure the safety and reliability of the equipment during use.
